Chapter 10 - Cell Growth and Division Flashcards
what determines the rate at which it uses food and oxygen?
the volume
each pair of chromatids is attached at an area called what
centromere
the period of growth in between cell divisions is called what
interphase
what is the cell cycle
a series of events that cells go through as they grow and divide
what happens during G1 phase?
cell growth
what happens during the S phase?
DNA replication
key proteins called histones synthesis
what happens at the G2 phase?
preparation for mitosis
doubles organelles
what happens during M phase?
cell division
what are the three phases that happen during interphase?
G1 phase
S phase
G2 phase
what are the four phases of mitosis?
prophase
metaphase
anaphase
telophase
what is the two tiny structures located in the cytoplasm near the nuclear envelope at the beginning of prophase. only in animals
centrioles
what grows more rapidly, the volume or the surface area?
volume
what is the process by which a cell divides into two new daughter cells
cell division
the production of genetically identical offspring from a single parent is known as what?
asexual reproduction
what offspring inherits some of their genetic information from each parent?
sexual reproduction
genetic information is bundled into packages of DNA is known as what
chromosomes
what happens during the cell cycle?
a cell grows
prepares for division
forms two daughter cells
what completes the process of cell division
cytokinesis
the division of a cells cytoplasm is called what?
cytokinesis
what is the final phase of mitosis?
telophase
what is a disorder in which cells loose thur ability to control growth and division?
cancer
what is the advantage and disadvantages of asexual reproduction?
advantage: many offspring in a short time
disadvantage: offspring adapted for same environment as parent
what are the advantages and disadvantages of sexual reproduction?
advantage: more likely to have offspring that will adapt to new conditions
disadvantage: must find a mate
